1966 Map of Coglan Buttes

USGS Topo · Published 1968

About this map

The Upper Chewaucan Marsh dominates this mid-1960s landscape, illustrating a complex system of water management in the high desert of Lake County. Through a network of engineered waterways including the Zx Brattain Ditch, Bagley Ditch, and Red House Ditch, the Chewaucan River is diverted to support vast ranching operations. Significant cattle ranching infrastructure is evident at the Zx Ranch Red House and the Zx Ranch Grain Camp, while the curiously named Chinatown Pump suggests localized history near the Stock Canal. To the east, the terrain rises sharply into the Coglan Buttes, where the elevation reaches over 5,000 feet, providing a stark vertical contrast to the level Alkali Flat below. This survey captures the working landscape of the Oregon outback, defined by its reliance on irrigation and isolated ranching outposts.
